Surgical site infections are amongst the leading cause of morbidity, mortality and cost due to increased hospital stay by patients. A study was conducted to understand antimicrobial susceptibility patterns of major pathogens isolated from surgical site infections in Belize.

To identify pathogens that are frequently isolated from wound infections in the Turks and Caicos Islands and formulate antibiogram based on their patterns of antimicrobial susceptibility. Bacteriology and antimicrobial susceptibility data from 1343 wound swabs cultured at the Cheshire Hall Medical Laboratory between January 2013 and November 2015 were retrospectively analyzed. The Kirby-Bauer disc diffusion technique was used to perform antimicrobial susceptibility testing. 79.1% of the 1343 swabs cultured were positive yielding a total of 1687 bacterial isolates. Frequently isolated bacteria included Staphylococcus aureus which accounted for 27.6% of isolates, approximately a third of which were methicillin resistant, Pseudomonas spp. (12.1%), Proteus spp. (8.2%), Enterococcus spp. (7.8%), E. coli (7.2%), Streptococcus agalactiae (6.1%), Klebsiella spp. (5.5%), Acinetobacter spp. (4.3%), coagulase negative Staphyloccus (4.0%) and Enterobacter spp. (3.7%). The overall highest resistance rates were seen among tetracycline (46.3%), erythromycin (37.6%) and ceftriaxone (34.2%). Imipenem, penicillin, meropenem and vancomycin had sensitivity rates ranging from 92.3% to 99.5%. Individual resistance rates varied among isolates, some differing significantly from overall rates. When tested against antibiotics routinely used to treat Pseudomonas spp., resistance rates ranged from 1.4-55.5%.

Biofilm is the layer which is formed with the matrix produced through accumulation of the free organisms on a proper surface. This layer makes treatment of S.aureus infections difficult as it makes S.aureus resistant to antibiotics and inhibits phagocytosis.

Irrational antibiotic use has led society to antibiotic resistance, a serious health problem worldwide. This study aimed to assess the prevalence of antibiotics self-medication among university medical students in Tripoli city.

Infection with Pseudomonas aeruginosa in cystic fibrosis (CF) patients is a strong contributor to respiratory failure and associated mortality. Bacteria colonizing a cystic fibrosis lung commonly form biofilms that greatly contribute to increased antibiotic resistance and hypermutability. Antimicrobial treatment in these cases can be either through the use of a single agent (monotherapy) or through a combination of agents (combination therapy).

β-lactam antibiotics represented the oldest class of antibiotics used in the treatment of infections in a human being, livestock, and aquaculture. Drugs residues in the edible tissues or foodstuffs of animal pose a potential threat to human health. At present, extensive antibiotic-resistant strains are now being detected and the development of antibiotic-resistant strains of epidemic and zoonotic pathogens is a major concern. Therefore, the purpose of this study was to estimate the extent of β-lactam antibiotics-HSA/BSA conjugations via three conjugation methods by using high-performance liquid chromatography (HPLC) with ultraviolet (UV) detector. We wish that the technique will be applied to preliminarily detect the residues of β-lactam antibiotics may persist in edible tissues or foodstuffs in the livestock and aquaculture farms in clinical.

Antibiotic usage is very popular in the clinical treatment to infective diseases resulting in the occurrence of antibiotic-resistant bacteria. Antibiotics are also extensively utilized in mariculture along the coastal area including the mangroves, however, the frequent usage of antimicrobial agents can induce to the bacterial resistance, and no research on this is found to date, as a result, the occurrence and distribution was investigated in Gaoqiao mangrove wetland, China in this research.

In animal production, antibiotics are used at sub-therapeutic and therapeutic levels for growth promotion and disease prevention. Using antibiotics can result in selecting for drug resistant microorganisms that may spread to humans through consumption of contaminated food. Lately, an increased interest in organic farming, where animals are grown without antibiotics, has been popular amongst the consumers. It is believed that organic farming will reduce antimicrobial resistance in microorganisms. However, the animals grown organically may be prone to diseases, and other microorganisms may thrive in the gut, that may be potentially harmful to humans. We analyzed the DNA of fecal samples of pigs grown under conventional and organic dietary regimens and detected the presence of genes that causes antibiotic resistance.

Antibiotics are one of the most widely used groups of drugs. The development of antimicrobial drugs represents one of the most important advances in therapeutics. Irrational and uncontrolled use of these agents both in developing and developed countries has resulted in an evolution of resistant strains in addition to a poor health outcome. Despite this fact, antimicrobial agents are vastly over-prescribed in the inpatient setting and the availability of antimicrobial agents without prescription in many developing countries. The use antimicrobial agents in Infants and children have become a routine practice for the treatment of pediatric illness and it needs study to show the status and pattern of antimicrobial in this age group is critical hence they are most vulnerable population groups to counteract illness

Streptomyces species are medically, industrially, and microbiologically important bacteria that are found in soils and other habitats. Streptomyces isolates and QUBC97 were cultured on a new medium (CCG). Agar plug diffusion test showed antibacterial activity. N-butanol extracts analysed by silica thin layer chromatography (TLC), HPLC purified and identified by MS analysis. QUBC97 was identified based on morphology, PCR, and DNA sequencing of two loci.

The face is the most vulnerable area in the dog bites, the disease is an infectious emergency, aesthetic and functional. we will discuss the clinical, therapeutic and evolutionary of dog bites. Our study focuses on 10 cases recorded over 3 years.

Apical periodontitis is caused by polymicrobial infection. The causative bacteria are generally organized into biofilms that adhere to the canal walls, and may include facultative bacteria such as Aerococcus and Enterococcus, which are the causative agents of several endodontic infections and have a natural resistance to many antibiotics including penicillin.

Cellulites of dental origin are extensive polymicrobial infections of the face and neck cell-adipose tissues. Management of infections of this nature presents significant challenges. The key to this is the identification of the causative organisms and determination of their susceptibility to antibiotics.
